Thank you so much for this video. I bought a C3 Complete on 29 April this year and there were no printed instructions in the box. Luckily I found your video as it shows the two filters. My Airclean filter looks different to the one in the video as it doesn't have the word REPLACE gradually showing as the filter gets dirtier. I turned the filter box over and the pad was black; so I replaced it. That's after using the vacuum about 27 times since I bought it. I'm a domestic cleaner and have 3 clients who prefer me to use my own vacuum cleaner. All the best to you.
I absolutely HATE how the bag pops out when the lid is opened. It is not obvious enough and the lid can still be closed when the bag is not correctly seated. Thank you for pointing this out. I did wonder why the dust spewed into the machine (twice).
Thank you, that was helpful in diagnosing a problem. I tried pressing the play button on the heap filter, and even pressed really hard, but nothing happened. The bottom of the HEPA filter is gray and is just over a year old so it does need changing-Just not sure why that little play thing is not doing what yours did.
